This project appears to analyze hotel booking data and perform various data cleaning and exploratory data analysis tasks. Here's a brief description of the steps performed:

Importing necessary libraries: Pandas, NumPy, Seaborn, and Matplotlib. Reading the hotel booking data from a CSV file into a Pandas DataFrame. Performing data cleaning tasks such as handling missing values, dropping unnecessary columns, and filling missing values with appropriate values. Analyzing the country of origin for the guests and visualizing it on a choropleth map using Plotly. Analyzing the prices of hotel rooms per night using box plots. Identifying the busiest months for resort and city hotels based on the number of guests. Visualizing the monthly trends using line plots. Analyzing the average daily rate (ADR) of hotels across different months using bar plots and box plots. Determining whether bookings were made for weekdays, weekends, or both, and visualizing the data using stacked bar plots. Creating additional features to improve the machine learning model's performance, such as identifying family bookings, calculating the total number of customers and nights, and encoding categorical features. Handling outliers in numerical features using log transformation. Assessing feature importance using Lasso regression and selecting the relevant features. Splitting the data into training and testing sets and applying logistic regression as a machine learning model. Evaluating the model's performance using confusion matrix, accuracy score, and cross-validation. Applying various other classification models, including Naive Bayes, Random Forest, Decision Tree, and K-Nearest Neighbors, and evaluating their performance. Overall, the project aims to analyze and understand hotel booking data, clean and preprocess the data, and build a machine learning model to predict hotel booking cancellations based on the available features.

The code written in Python script for data cleaning and analysis of a hotel bookings dataset. It performs various tasks such as data cleaning, missing value imputation, visualization, feature engineering, feature encoding, feature selection, and model training.

Importing necessary libraries:

The code reads the hotel bookings dataset from a CSV file using the pandas read_csv function and assigns it to a DataFrame named df.

The code performs several data cleaning steps, including handling missing values and removing irrelevant columns. It drops the 'agent' and 'company' columns using the drop function. It fills the missing values in the 'country' column with the mode value using the fillna function. It fills all other missing values with 0 using the fillna function.

The code includes several sections for analyzing and visualizing different aspects of the dataset. It explores the home country of guests by analyzing the 'is_canceled' column and creates a choropleth map using the Plotly library. It analyzes the prices of hotel rooms per night using box plots. It identifies the busiest months for resort and city hotels by analyzing the 'arrival_date_month' column and creates line charts using Plotly. It analyzes the average daily rates (ADR) in hotels by month using bar plots and box plots. It explores whether bookings were made for weekdays, weekends, or both, and creates stacked bar charts to visualize the data.

The code creates additional features to improve the machine learning model's performance. It creates a binary feature 'is_family' based on the number of adults, children, and babies. It calculates the total number of customers and total number of nights using the 'adults', 'children', 'babies', 'stays_in_week_nights', and 'stays_in_weekend_nights' columns. It maps the 'deposit_type' column to numerical values using a dictionary. It drops unnecessary columns and combines the categorical and numerical features into a new DataFrame named 'dataframe'.

The code performs feature encoding to convert categorical features into numerical format. It calculates the cancellation rate for each category and maps it to the corresponding categories in the DataFrame.

The code handles outliers by applying a logarithmic transformation to the 'lead_time' and 'adr' columns.

The code uses the Lasso method to select important features for the machine learning model. It selects features with non-zero coefficients from the Lasso model and updates the 'x' DataFrame with the selected features.

The code splits the dataset into training and test sets using the 'train_test_split' function. It trains a logistic regression model on the training data and makes predictions on the test data. It evaluates the model's performance using a confusion matrix and accuracy score. It also performs cross-validation to assess the model's performance using the 'cross_val_score' function. The code then trains and evaluates several other models, including Naive Bayes, Random Forest,

This code snippet performs various data cleaning, analysis, visualization, feature engineering, feature encoding, feature selection, and machine learning techniques on a hotel booking dataset.
